2014年5月托福考试模拟试题及答案(第六套)_第2页

　　Reading:【课文要点】：生物学术语resource partition (资源分区).

　　意思是在同一特定的habitat或吃同种事物的动物们可以互相不争夺食物资源，基于他们自己的physical character,，可以和平相处。

　　Listening:【教授举例】：教授举了美国北部某地的生活在pond的两种鸭子blackhead和redhead，

　　都吃insects 和 grass, 但是不互相争夺，因为细究来看，它们的食物还是有slightly不同，

　　这是由它们physical character造成的。

　　1)blackhead鸭嘴长，可以伸进深水猎食，所以多在池塘中间深水处活动。

　　2)redhead嘴短，只能在池塘边上的浅水区觅食。

　　Sample answer:

　　In this set of materials, the reading passage explains a definition of resource partition. It states that animals in the same habitat can share the same food resources and get along well with each other based on their physical character.

　　In the listening passage, the professor gives an example to further explain that. He brings up the fact thattwo kinds of ducks--- blackhead and redhead living in one pond all eat insects and grass, but they never fight over that. He goes on to illustrate that their food is slightly different due to their different physical character. Blackhead ducks have long beak, which can make them get food in the deep water. Redhead ducks have short beak, which makes it possible for them to get food in the low water around the sides of the pond.

　　By these means, he proves that animals living in the same habitat share the territory and the food instead of competing against each other.

　　【学生困难】：男女生要去参加一个play的准备rehearsal，但director要走人，因为 bad temper，跟其他人无法共事，自己老蹿火。但有一个candidate可以, 可是又sick 了.

　　【解决方案】：两个方案：1)自己演自己导. 2) 极力劝说那个火爆脾气别quit，因为是最理想的director.

　　Sample answer:

　　This is a discussion between two students who are going to attend a rehearsal of a play。But the director is leaving because of his bad temper. One of the solutions the two students come up with is that they have to be their own director ‘cause a candidate who can direct is sick. The other solution is to try to persuade that

　　bad-tempered director to get back ‘cause he is the most ideal one. I tend to agree with the second solution because the sick substitute might not get the job well done. And also the original director may not lose his temper all the time.

　　【讲课要点】：教授讲经济学demand，先一句话定义了一下，然后她说产品价格上升，需求下降，两个原因，拿coffee 作例子，当有一种substitute存在时比如tea，咖啡价格升，人们买茶，咖啡需求自然就下降了;但没有tea或者人们就偏爱咖啡，价格升后，人们还会买咖啡，但买的数量少了，总体需求也下降了。

　　Sample answer:

　　In the lecture the professor tells us about demand in economics and explains that products are less demanded when the price is high and vice versa. There are two causes. One is the substitution effect; the other is consumer tastes. Then she takes coffee for example. When a substitue like tea exists, customers may buy it if the price of coffee increases. Then the demand for coffee decreases. However, when there’s no tea or people just love to drink coffee, they will still buy coffee even though the price of coffee goes up. But the purchased quantity drops, and thus the overall demand falls.
